垂直轴风力机因其结构简单、无需迎风、传动简便、制造容易、成本低等优点而备受关注。垂直轴风力机通常可分为升力型和阻力型两大类。一般来讲,升力型风力机的风能利用率较高,而阻力型风力机的风能利用率较低。然而,直叶片升力型垂直轴风力机因某些相位处的启动扭距小,有时需要通过电机带动才能启动。本文应用计算流体力学方法,研究了一种螺旋升力型风力机,结果表明:螺旋型风力机不但具有较高的气动性能,而且具有较好的启动性能。 Vertical axis wind turbine because of its simple structure, no need to wind, simple transmission, easy to manufacture, low cost and other advantages and much attention. Vertical axis wind turbine can be divided into two types of lift and resistance. In general, lift-type wind turbine wind energy utilization is high, while the resistance-type wind turbine wind energy utilization is low. However, straight-blade lift type vertical axis wind turbines have a small starting torque at certain phases and sometimes need to be driven by a motor to start. In this paper, a spiral lift wind turbine is studied by computational fluid dynamics. The results show that the spiral wind turbine not only has higher aerodynamic performance but also has better starting performance.
